Hauv me me - cov kua dej ntsuas, cov khoom siv hluav taws xob yog qhov tseem ceeb "throttle" rau kev ua haujlwm. Txawm hais tias koj tab tom siv lub tshuab hluav taws xob los ntawm ib qho Li- ion roj teeb (3.7V) lossis kev tswj hwm 6V rail, kev nkag siab txog kev sib raug zoo ntawm qhov hluav taws xob thiab tus nqi ntws yog qhov tseem ceeb rau kev ruaj ntseg.
Phau ntawv qhia no txheeb xyuas seb cov twj micro dej teb li cas3V, 4V, thiab 6Vinputs thiab yuav ua li cas optimize koj xaiv rau efficiency thiab lifespan.
1. Lub Physics: Vim li cas Voltage Dictates Flow
Feem ntau cov twj micro twj yog tsav los ntawm DC motors. Kev sib raug zoo tseem ceeb yog tswj hwm los ntawm lub cev muaj zog tas li (Kv ):
Kev sib hloov ceev (RPM): Nws ncaj qha proportional rau qhov voltage (V). Thaum koj nce voltage, lub cev muaj zog spin sai dua.
Flow tus nqi (Q): Rau diaphragm thiab centrifugal twj tso kua mis, tus nqi ntws nce ze li linearly nrog RPM.
Kev lag luam - tawm: Siab voltage nce ntws tab sis kuj exponentially ncetam sim no kos (I)thiabkub tiam.
2. Voltage Sib piv: 3V vs . 4V vs . 6V
| Qhov hluav taws xob | Flow Performance | Kev siv fais fab | Qhov zoo tshaj plaws siv Case |
| 3V | Tsawg (Tseeb) | Ultra - Tsawg |
Wearables, Roj teeb -cov khoom ua si muaj zog |
| 4V | Nruab nrab (Balanced) | Nruab nrab |
Ntse tsev diffusers, PC txias |
| 6V | Siab (Max Output) | Siab |
Kas fes tshuab, tshuaj tsuag tshuaj |
3V: Lub Zog-Txuag
Ntawm 3V, lub twj tso kua mis ua haujlwm ntawm nws qhov ntsiag to thiab txias tshaj plaws. Qhov no yog "safe zone" rau cov khoom siv uas xav tau roj teeb lub neej ntev tab sis tsis tshua muaj suab nrov.
4V: Qhov Chaw Zoo
Feem ntau cov kev khiav hauj lwm voltage rau lithium{0}}powered li (3.7-4.2V). Nws muaj qhov sib npaug zoo tshaj plaws ntawm cov dej ntws zoo thiab tswj tau thermal tso zis.
6V: Kev Ua Haujlwm Peak
Ntawm 6V, koj mus txog lub twj tso kua mis siab - qib kev ua tau zoo. Qhov no muab lub taub hau siab tshaj plaws thiab ntws tus nqi tab sis yuav tsum tau ua tib zoo saib xyuaskub dissipationthiab txhuam lub cev muaj zog (yog tias tsis siv BLDC).
3. Yam tseem ceeb cuam tshuam rau qhov hluav taws xob teb
Pump Topology: Diaphragm twj tso kua mismuab ib tug heev linear ntws nce, whereascentrifugal twj tso kua mistej zaum yuav pom ib tug cubic nce nyob rau hauv hwj chim noj raws li ceev nce.
System Backpressure: Yog tias koj lub tubing nqaim, nce qhov hluav taws xob los ntawm 4V mus rau 6V tsuas yog nce cua sov, tsis ntws, vim cov dej tsis kam.
PWM Control: Hloov kho 6V, ntau tus engineers sivPulse Width Modulation (PWM)mus rau "digitally" kho qhov voltage, tso cai rau kev khiav ceev tswj tsis tau kho vajtse hloov.
4. Yuav ua li cas xaiv lub twj tso kua mis rau koj qhov hluav taws xob Rail
Txheeb xyuas P-Q nkhaus: Ib txwm xa mus rau cov chaw tsim khoom cov dej ntws- lub taub hau nkhaus ntawm qhov tshwj xeeb voltages.
Tus account rau Voltage Sag: Yog tias siv cov roj teeb, nco ntsoov tias lub roj teeb "3.7V" poob rau 3.0V thaum nws tawm; xyuas kom koj lub twj tso kua mis tseem tuaj yeem ua rau qis qis.
Ua ntej BLDC rau 6V +: Rau kev siv tas li ntawm 6V,Brushless DC (BLDC)motors raug pom zoo kom tiv thaiv ntxov ntxov lub cev muaj zog tsis ua hauj lwm vim siab -kev sib txhuam ceev.
Vim li cas PinMotor yog tus nyiam koom tes rau qhov hluav taws xob -Cov haujlwm tseem ceeb?
Dav Voltage Compatibility: Peb cov twj tso kua mis yog tsim los ua haujlwm ruaj khov thoob plaws ntau qhov kev tawm tswv yim (los ntawm 2.5V txog 12V).
Cov ntaub ntawv Precision: Peb muab cov ntaub ntawv pov thawj tseeb-tam sim no-voltage cov ntaub ntawv, tso cai rau koj cov engineers simulate fais fab nyiaj txiag kom raug.
Kev cai Winding: PinMotor tuaj yeem kho lub cev muaj zog windings kom ua tiav koj lub hom phiaj ntws ntawm qhov tshwj xeeb, tsis yog - tus qauv voltage.
ISO 9001 Zoo: 100% kev kuaj xyuas kom ntseeg tau tias kev ua tau zoo sib xws thoob plaws txhua pawg, tsis hais qhov kev khiav hauj lwm voltage.
FAQ: Voltage thiab Flow Rate
Q1: Puas yuav dhau -volting lub twj tso kua mis 3V rau 6V puas rau nws?
A: Zoo li yog. Tshaj -volting ua rau kub hnyiab tau ntau dua thiab tuaj yeem yaj cov khoom sab hauv lossis hlawv tawm ntawm lub cev muaj zog. Ib txwm nyob hauv qhov ntsuas ntsuas.
Q2: Kuv puas tuaj yeem siv PWM los ua lub twj tso kua mis 6V coj zoo li lub twj tso kua mis 3V?
A: Yog. PWM zoo txo qis qhov nruab nrab qhov hluav taws xob, tso cai rau koj ua tiav 3V- sib npaug ntws thaum tuav lub peev xwm "boost" rau 6V thaum xav tau.
Xaus: Engineering rau Efficiency
Voltage tsis yog lub zog xwb; nws yog ib qho kev ua haujlwm regulator. Los ntawm kev sib piv koj lub twj tso kua mis cov yam ntxwv voltage rau koj lub cev cov dej xav tau, koj tuaj yeem ua kom muaj txiaj ntsig zoo tshaj plaws thiab txuas ntxiv lub neej ntawm koj cov khoom.
